CHAIR.

SPECIFICATION forming part of Letters Patent No. 449,114, dated March 31, 1891.

Application filed August 6, 1888. Serial No. 282,035. (No model.)

To all whom it may concern.-

Be it known that I, ERASTUS S. FRENCH,of Princeton, in the county of tVorcester and State of Massachusetts, have invented a new and useful Chair, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a sectional elevation of a chair embodying my invention when adapted for use as a high chair; Fig. 2, a sectional elevation of the same when adapted for use as a low chair. Fig. 3 is a plan, and Fig. 4: a rear elevation.

My invention relates to that class of chairs which are called con vertible chairs, because adapted for use either as a high chair or as a low chair or carriage. Chairs of this class have long been known and have been constructed on a variety of plans.

My invention consists in the combination of a chair-frame a and a supporting-frame b, by means of braces d, which at one end are pivoted to the chair-frame a and at the other end to the supporting-frame b, and which, in connection with the cross-piece 1), supports the chair-frame a in its elevated position and also permits the chair-frame a (when its crosspiece a is disconnected from the cross-piece b) to be moved down until the chair-frame a rests upon the cross-pieces 1) b as pointed out hereinafter.

In the drawings, the chair-frame CL is connected to the cross-piece b by means of pins I I and the hook 2. While this is a simple and ready means of connecting the chairframe a with the upper portion of the supporting-frame b, it will be obvious that there are many other fastening devices equally applicable.

lVhile I prefer to make the supports 1) b cross-pieces of the frame b, it will of course be obvious that itis not essential that they should extend clear across the frame I), but only far enough to serve as stops'for the chairframe a.

It is convenient to construct the table commonly used in chairs of this class in two poi tions ff, one portion being pinned to one arm a of the chair and the other portion to the other arm a so that when moved on these pins the two portions meet and form a complete table, as clearly shown in Fig. 3.

When it is desired to use the low chair as of the frame 17, and the bail or push-handle g, havingavheels 4: at its lower end,is pivoted to the frame Z) in a manner so that when the push-handle or part marked 9 is moved to bring it into position to be used as a pushh'andle (see dotted lines in Fig. 2) the wheels 4 at its lower end are swung into position to support the rear of the chair and to raise the rear legs of the supporting-frame from the floor, the push-handle being pinned at 6 to the link '7, which connects the wheels 4 to the frame I).

I am aware of Letters Patent No. 188,120 to French et al., March 6, 1877; No. 231,689, to Stevens, August 31, 1880; No. 244,014, to lVilliams, July 5, 1881, and No. 220,258, to Stevens, October 7, 1879, and disclaim all that is shown in them, my chair differing radically from the chairs shown in said patents in that my chair belongs to that class of convertible chairs in which the supportingframe is always upright and does not require to be turned ninety degrees when the chair is changed from a high chair to alow chair or from a low chair to a high chair. The chairs shown in the above patents belong to another a carriage, wheels 3 are connected to the front class in which the supporting-frame does require to be turned ninety degrees when the high chair is converted into a low chair, and vice versa, and all chairs of this class I dis claim.

What I claim is The chair above described, composed of chair-frame a, supporting-frame 5, provided with supports Z) Z) If and braces d d, the braces d d being connected at one end to a portion of the supporting-frame b and at the other end to a portion of the chair-frame a to allow the chair-frame a to swing downward on supports b b to form alow chair, and support I) being at an upper rear portion of frame Z) to support the rear of the chair frame (0 when it is in position to serve as a high chair, the above combined with a device for locking frames a and I) together when frame a is in position for a high chair, all substantially as and for the purpose set forth.
